LICENSE-NUMBER-DISPLAY DEVICE.

Application flied April '16. 1915.

To all whom, it may l-(mrcrn:

Be it, known that 1, CHARLES H. Gimn- BERG, a citizen of the United States, residing at Dover. in the county of Morris, State of New Jersey, have invented certain new and useful Improvements in License-Number- Display Devices; and l do hereby declare the following to be a full, clear. and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention. relates to devices for displaying the license numbers of automobiles.

The object of the invention resides in the provision of a device of the character named embodying an improved construction whereby the license number of an automobile can be displayed with equal clearness in either daylight or darkness.

With the above and other objects in view the invention consists in the details of con-- struction and in the arrangement and com bination .of parts to be herein more fully described and particularly pointed out in the appended claims.

In describing the invention in detail reference will be had. to the accompanying drawings wherein like characters of reference denote corresponding parts in the, several views, and in which Figure l is a view in elevation of a license number display device constructed in. ac cordance with the invention;

Fig. 2, a rear view of the device;

Fig. 3, a section on the line 3 3 of Fig. 1, and

Fig. 4. a section on the line -t-l of Fig. 1.

Referring to the drawings the device is shown as comprising a casing A to which is secured L-shaped brackets 10 whereby the device may be convei'iiently secured to the rear of an automobile. The casing A is provided with a removable front B which comprises a frame ll,having dctachably cured therein an outer number panel 12 and an inner number panel 13. The outer mun ber panel 12 is formed of suitable transparent material upon the inner side of which is applied an opaque material in such manner as to leave the numbers and letters of the license transparent. The inner number panel is formed preferably of white china through which rays; of light can penetrate a subdued manner. By this construction Specification of Letters Patent.

it will be apparent that in daylight the num bers of the license will appear clear white and will be displayed with. equal clcarncss in darkness when the interior of the casing A is illuminated. This illumination is of fecterl through the medium of the usual tail lamp l-l which is secured to the casing Ft through the medium of bracket arms 15 attached to the roar of the casing A. The light of the lamp I is delivered into the casing A through an opening 16 in one end of the casing. A reflector 17 is mounted in the casing A for the purpose of directing the light against the panels 12 and 13.

The reflector. asshovvn in the drawing, can be removed from the using A through the open end 16 thereof, when the lamp 14 is removed from the casing, this end being flared as will be obvious, but said reflector is normally held within the casing through engagement with the lamp as illustrated in Fig. 3 of the drawing. The reflector has its end distant from the lamp curved toward the front of the casing and this curved end engages the closedcnd of the casing. The reflector is thus held immovable between this end of the closed casing and the lamp. It will be understood of course that this provision for the removal of the reflector permits oi the cleaning of the latter Without detachin the front B with resultant danger of breaking the plates 12 and 13.

\Vhat is claimed is:-

1. A license number display device comprising a box-like casing open. at its front and having a flared open end, a frame fitted on the open front and having transparent and translucent symbol sections carried thereby, a refle tor removably fitted Within the casing and having a flared portion engaging the flared open end of said casing and extractable through said open end, a bracket carried by the casing at the open end. and a lamp detachably fitted on the bracket nd having a front flared and abutting the flared open end of the casing to hold the reflector within said casing, said lamp being arranged to direct its light into the casing through the open end of the lattklanll between the reflector and the front portion of the casing.

2. A license number display device comprising a box 'casing open at its front and aving a flared open end, a frame fitted on the olen'front and having transparent and the same and directing light through the trans ucent symbol sections curried thereby, open end of the letter. 0 a reflector removal) fitted within the eas- In testimolrv \vliereo'f, I aflix my signainguand having a ared portion engaging ture, in the presence of two witnesses.
